Female Gender is not a Risk Factor for Early Mortality after Coronary Artery Bypass Grafting

Background: The female gender is considered as a risk factor for morbidity and mortality after coronary artery bypass grafting (CABG). Aim: In this analysis, we assessed the impact of female gender on early outcome after CABG. Study Design: This is a retrospective analysis of data from our center situated in South India. Statistical Analysis: Patients were categorized according to gender and potential differences in pre-operative and post-operative factors were explored. Significant risk factors were then built in a multivariate model to account for differences in predicting gender influence on surgical outcome. Methods: 773 consecutive patients underwent first time CABG between January 2015 and December 2016. 96.77% of cases were performed using off-pump technique. 132 (17.07%) patients were females. These patients formed the study group. Results: The in-house/ 30-day mortality in females was similar to that of males (3.03% vs. 3.12%, p value 0.957). Mediastinitis developed more commonly in females (5.35% vs. 1.30%; p value 0.004) compared to males. There were more re-admissions to hospital for female patients (21.37% in females vs. 10.14% in males, p value
